This invention relates a boat andpartiou- 'larly pertains to a; sectional and' porta'ble-boat structure.

Various types of boats have been made which have been portable, and some of them have been 3Claims. ((31.9-2) I 'wa'll 12. ;Veitic'a1 ibs H- ar cast inte 'mi "with sectional. Theyhave forthe most part been impractical and flimsy in construction. It is desirable to provide a lightweight boatstru'cture for civilian and military operations, and it is the principal object of the present invention to provide a boat which is made in rigid strong sections, each of which is light in weight, and which sections may be 'easily'locked together to form dled separatelyand to be assembled easily so that they may assume the positions and function of the fore and aft portions of a boat, and when desired with supplemental center portions.

The invention is illustrated by way of example .in the accompanying drawing in which:v

Figure 1 is a view in plan showing an 'assembled boat, such as a row-boat or motor boat, in which the fore and aft sections are secured together.

Fig. 2 is a view in side elevation showing the structure as indicated in Fig. 1.

Fig. 3 is a view in plan and diagram indicating the manner in which a plurality orsupplemental sections may be interposed between the forward and rearward portions of the boat to increase the capacity and length of the structure.

Fig. 4 is a view in vertical section as seen on the line 44 of Fig. 1, showing the manner in which the fore and aft elements of the boat are joined.

Fig. 5 is a view in longitudinal vertical section as seen on the line 5-5 of Fig. 1 and shows the interlocking elements of the boat as when separated.

Fig. 6 is a side view of the bolt for locking the sections together.

Referring more particularly to the drawing, I indicates the forward section of the boat and II indicates the rearward section of the boat.

The forward section is formed by a hull wall I2 "boat."

Formed integral with" he bulk'heaiis l3fare "bosses I3 each; offwhich; is a central opening I 9 terminating in upper and lowerrecesses I 9 There are'two such bosses dispos'ed'nearthe sides 'of the hull." Thelongitudinaljopenings I9 iii-the bosses I8 are adaptedto accommodate king bolts ,20. These 'bolts are formed at their "lower' ends with a square portion 2I. 'The lower ends of the portions 2 I 'are' inclinedls'o that theyfwillconform to the outer'contour of-"the hull-'I 2. The upper ends of the king boltsare' tlir eaded at '23 and receive a nut 2'4 which is forked to accommodate a handle 25. I The handles are pivoted at :26

'to the fork of the nut-24. Each of the handles 23 carries a locking plunger-21 which is forced yieldably into an opening 28 by a" spring 29-. "The rearward'sectidn II of'the boat includes hull walls I2 which'are joined at the stern by a wall 30 and at their 'forw'ard ends by a bulkhead 3L 'This bulkhead extends transversely of the hull and is formed integralwith a'horizon- 30 are 'forrned i'ritegral with 'a seat I6".'= "-Rei-nforcing ribs I1 are formed integral with the wall I 2' and bottom I4 to strengthen the hull structure. Extending horizontally from upper and lower edges of bulkhead 3| are bosses 32 and 33. The boss 33 is formed with a bore 22 which is adapted to receive the portion 2| of the bolt 20. When sections II and I2 are juxtaposed as shown in Figs. 1 and 2, the bolt 20 extends upwardly through longitudinally aligned bores 34 and 35 which are formed through the bosses 32 and 33. At the upper end of the bore 34 there is a counterbore 36 which receives the nut 24. The section II is reinforced by vertical webs A formed integral with bulkhead 3| and seat I5 in the longitudinal planes of the bosses 32 and 33.

It will be obvious that it may be desirable to assemble the boat structure by using one or more sections 31. These may be inserted between the forward and rearward sections I0 and II to provide additional length or capacity for the boat. The manner in which the sections III, II and 31 are assembled is the same as that for sections 19 and I I above described.

In operation of the present invention the boat sections are constructed as shown in the drawing so that the portions I0 and Il may be assembled as indicated in Figs. 1 and 2. When this is accomplished the bolts 20 are inserted through so the openings IQ of the members I8 as well as t rue urea d si e e ha e show he-- rferriom e m in s edn through the bores 34 and 35 ot the bosses 32 and 33. vWhen it is desired to fasten the boat structure in its assembled position the nuts 24 arescrewed onto the threads 23 and the handles 25 are used to apply torque to the nuts. As the nuts are tightened the square portions 2| are drawn upwardly and then the handles 25 are swung downwardly from their dotted line positions to then-horizontal positions. At this time the plungers 21 will extend downwardly into the openings 28 and will be held in the openings 28 by means of spring 29. This will lock the handles 25 against movement around 'the'axis of the bolt 20. The sections l and II, and possibly the section 31, will thus be rigidly held .togetherto form a boat structure. Thisstructure may be used as a roweboat or it may be used as an outboard motor boat. It will thus be seen "that. the boat here disrins d-is c mbine a; ctions which li in weight 1..i20s .s ;isi er b i tr ng h end Qwhlch maybe easily assembled together to form .,-a-s ne nown tofi e. i ill be und tyarious-changes may be madeincombination, construction and arrangementof parts by-those skilled in the .art, .without departing from the spirit of the invention :as-c'laimed. -,Having ,thus described my invention, what I eleimand de i t sec re by te s at -1s:
